Abstract
A bearing system that includes a superconductor bearing and a magnetic rotor that can carry a load. The bearing system exploits the Meissner effect to levitate the magnetic rotor. The magnetic rotor can rotate or translate with respect to the superconductor bearing in response to an applied external force or torque. Advantages of the bearing system are that a coefficient of friction developed in the interface between the superconductor bearing and the magnetic rotor is approximately zero, and the bearing system may be used for vibration isolation and non-mechanical coupling.
